2nd Generation Dodge 24 Valve Powertrain

Finally happy again with my injectors and power. Many years ago, ran DAP +60hp VCO injectors, they were pretty clean usable. Then some DFI 7x.009 +100hp VCOs, clean and powerful. Then DAP 7x.009 SACs, smokey and laggy with the super b, tuner or no tuner. Now I have about 50 miles on some Contageous 7x.008 RV275 stlye +50hp SACs, very clean and powerful with no tuner, slight haze romping on it with tuner off, and only a touch of smoke till boost builds with the tuner on. Super b is definitely more laggy than the holsets, but burns clean with rpms. Smaller injectors with the tuner off is streetable down low, and then turn the quadzilla xzt after you get rolling.…

I had installed a rebuilt blackwater long block about 120K ago. at about 30K i had a leaking head gasket and installed new along with fire wire? not fire rings along with arp studs. I have easy edge and rv injectors and 4inch straight all in a 99 club cab dually 2 wheel drive,6 spd. My problem started after i had a friend drive a load for me, I have a pyro guage and light on guage is inop. so advised him not to run her over 1000 and check guage at night in the hills with a light etc. My guess is he ran it up and possibly caused my now blowby. What temp is safe? Could i have a head gasket failure causing the blowby? I understand weak rings or score does cause blowby but wo…

I have an 02 cummins ext cab short bed 4x4 with an auto. Truck was foggy and lost all power. Had codes P1698 P1689 P0237 which myself and mechanic buddy thought it was a bad vp44. So we replaced it with a new one from thouroughbred. Anyways he put it on and all the codes are still there and nothing has changed. I don't know what to do next!! Also have an airdog raptor and at WOT it still has 8psi

So, back before I deployed I used to have to wait for my WTS light to come on. Usually around 5-7 seconds. Started preparing to buy a new ECM for when I got back --- While I was gone I let my co-worker have the keys to my truck, after 2 weeks of being gone he said he killed my brand new Optima red tops that I put in 2 months prior to leaving . Luckily Advanced replaced both of them free of charge and I told him to just keep them on a trickle charger until I got back. The truck went without any kind of battery connected to it for around 5 and a half months. When I got back I put the new batteries in and fired her up and drove away. I've been driving it for about a month no…

Just wanted to touch base here and Say a Big Thank-You to Everybody! Big Blue ran fine across county last Nov! Pulled a 2 axle U-Haul across the I80 rte with out issues. Arrived in Klickitat County, Wa. after 4 days. Replacing the APS and alternator seemed to do wonders for the truck. The OSC radiator has performed very well,, even with the mercury hitting 112 here early this month! Looks like We will be heading back east in Nov, with Our destination being the Pike County, Pa area. Hope to pull a 2013-14 Dodge Avenger behind us... While I'm here, the lift pump pressure I installed last Summer is leaking out of the end where t…

So forgive me if this has already been discussed but I went back 20 pages and didn't see anything to help. 2001 HO 6-speed. FASS DRP, 75hp DAP injectors, Quad XZT+. New PCM a couple of months ago because I had been running an external voltage reg but hated the flickering lights and engine lope at idle. I replaced the vp44 with one from DAP 2yrs ago after intermittent stalling at highway speeds. Ran fine with 2-3 instances of a 1 sec miss at highway speeds last summer. thought this was possible injectors as it has 215K on originals so replaced them 7 months ago. this July when it hit 95+degrees I stepped on clutch to turn at an intersection and the truck died. …

At Les Schwab to buy a set of M-55's and switch from the old and corroded aftermarket aluminum dully wheels to stock steel and found out that my lugnuts will not work with the stock wheel and that i need to buy a set of 32 lugnuts at $11 bucks a piece. Can any one help? On a side note i am thinking of putting a second fuel tank in place of the spare tire. direct me to a old thread or chime in. My idea is to have the second tank feed into the stock one, so when the stock tank gets dry flip a switch and refill it with the second tank.

Started up my truck a few weeks back and I heard a loud pop and hiss...I thought it was just an issue with fuel as the truck was sitting for awhile. Get back in it a week later and run AC and it's not blowing cold at all so I blew something up. Hopefully just a hose. Any way to pressurize the lines with air to leak check?

I have an NP 241 DHD that has 2 cracks in the back of the case. All i am seeing for sale is NP 241 DLDs. Does anyone know if that back of the cases are interchangeable? Thanks Matt

So I installed my 7x.0105 injectors last weekend but ran out of time to do my airdog and sump. It always seems to be the boss lady has stuff for me to do when I want to work on my truck so yet again I'm only left with Sunday to play. was a pretty straight forward install on the injectors seeing as my day job is a diesel tech so was a walk in the park for me. Had them in and set the overhead in about 2 hours. Truck runs awesome, but I'm glued to my FP gauge and getting on it obviously the pressure was dropping more than I liked. Drive it nice and it stayed right around 10 psi. Still I needed to install the airdog just was waiting for the weekend to come. I gather…

I was under the truck today for other reasons and turns out my slave cylinder is leaking! I know they're easy to replace, and relatively cheap at NAPA, but has anyone else had this happen? Seems so strange for the slave to start leaking, but then again the truck is mad it's been sitting...

Well thinking my VP44 died during injector install. Background; Truck 2001 Dodge 2500 5.9 with 302K miles, DS Power puck, and FASS DDRP-02 that delivers 17.5 psi at idle and 15 psi at WOT. I replaced my tappet cover gasket about two months ago and needed to remove the VP44 at the time, looked at the data plate, and thought I took a picture of it, but didn't. It looked to be the original VP44, didn't notice and rebuild information. Restart went as expected bleed the system, cranked several time fired and ran fine. Then about a couple weeks ago, I decided to install a set of Bosch RV275 injectors. Install went as expected, torqued hold down bolts to 89 i…

hey guys I'm having an problem with my vacuum hose its all the way broken and now my cruise control stopped working and the ac is only blowing out of the defrost. i know this is coming from one of the vacuum hose just have and hard time trying to fix it or finding where i could get an replacement without having to go to the dealer cause we all know they are rip offs... any info would be helpful I'm in texas as the summer is here and its about to get hot...

Now I know this has been covered a lot, but no one could ever really answer the question I have. Figured I'd ask here since we have our own oil expert on board. I know the change interval in the manual says 7500mi. My situation in a bit different being my truck only sees ~ 5000 mi. a year. It is a work truck and I usually only use it to pull trailers and haul. It does not see a lot of highway driving either. I use Rotella 15-w40 and change twice a year or every 2500 mi. Can I change only 1 time a year and be safe? Should I go to synthetic if I only change once a year? Our mech at work is old school and still believes in the 3 month 3000 mi. thing. Some of the vans there m…

Hello everyone.. I'm lost and hope someone has experienced this before!! Bought a rollover truck and came with half ton body. Swapped body and pcm. Original chassis and engine wiring.. Knew vp44 was shitty before swap.. Tried to start it anyway.. No dice.. So a known good vp was installed. Truck still wouldnt start.. Shows batt voltage at the plug with it plugged in and cranking or not... Cut wires off plug, hot wired truck 6/7 pins while plug still connected.. No start.. Unplug the connector and hotwire truck fires right up.. Seems like something is keeping the truck off in the computer.. Shut off wire blue with red already cut off too... Help!!!!

Ok building a nv4500 and am wondering about the fifth gear nut is there a proven fix for it that dont require welding it? Or is one better of to leave it alone

I should get my 01 running this weekend. It's been sitting 11 months without any fuel and jacked up. (I was in process of upgrading fuel system and other things in life got in the way) Fuel was bought couple months before I perked it. So fuel (25 gallons) is over 1 year old and was stored in 5 gallon plastic cans in car port. And I also changed fuel tanks. Installing an Air Dog 100 and a carter pump as a back up, fuel has been cycled through filters probably 2 or 3 times. The "new to me" fuel tank not as clean as my old one (but no more sump and I'll never have one again) Because "new" tank still has stuff in it even after getting as clean as I could…

Do new fan clutches need time to "break in?" I got a new one Sunday night and it still hasn't unlocked by today so I took it back and got another. The new one hasn't unlocked today either so I'm not sure if I just need to give it some time or go get another.

As the title states, I while installing my Wicked Wheel on my HX35W I snapped the tip of the shaft off getting it tight. I know the instructions say to get it hand tight but it was seized and would not spin freely at all. The tighter I got it the looser it got and spun a little more freely until it snapped. It's for a 99 manual truck. I'm not trying to buy anything that's not genuine, I would buy just the center piece but my exhaust housing has been rusted to the point where it will not budge and I need to clock it for the compound turbo setup.

I have a 01 cummins was in a hurry this morning went to pass Someone and covered the road in smoke. Truck is bone stock straight piped.
